In the center of the underground secret room, Ye Nan had already asked people to move the Dan furnace from home.

At this time, the alchemy furnace had already been cleaned and placed there by his subordinates, and the oxygen tank was also filled with liquid hydrogen and oxygen again!

However, Ye Nan was still not careless, after all, the pill to be refined this time was not an ordinary Heavenly Spirit Pill or something, but a Nebula Pill that had not appeared in the cultivation world for hundreds of years, and this time the refining was only allowed to succeed and not fail.

If you fail because of insufficient preparation in advance, you will regret it, after all, it is extremely difficult to get together the materials.

Ye Nan carefully checked the alchemy furnace again, and after confirming that everything was normal, he was ready to start alchemy!

Carefully take out the materials in the ring one by one and place them on the small table next to the alchemy furnace. Ye Nan carefully cleaned up these elixirs that were unavoidable in the eyes of ordinary people.

Five jade boxes were placed in the center of the small table, among which Tianxing Grass, Water Cloud Grass, Extremely Rare Grass Fruit, Amethyst Ground Elm, and Extreme Ice Lotus totaled five flavors, and then another small jade bottle contained the last flavor of the Black Crowned Spirit Snake Gall!

These six flavors of immortal elixir were placed together, but they exuded all kinds of strange fragrances, some were rich, and some were elegant, which caused Ye Nan to swallow his saliva!

Ye Nan looked at these elixirs, how many or how few, and couldn't help but sigh lightly, there are still six leaves in this Heavenly Star Grass, and there are also five leaves in the Water Cloud Grass, only the Extremely Rare Grass Fruit and Amethyst Earth Elm are only as many as three or four, and the Extreme Ice Lotus has a total of twenty-one at most.

As for the black-crowned spirit snake gall, of course it's just that!

I thought about the Nebula Dandi recipe in my mind. But he couldn't help but sigh lightly. Originally, I could have refined some more land. It's just this extremely rare grass fruit and amethyst elm. It has been consumed quite a bit. There are only two or three left. If you want to refine that batch in hand. But it's a little less.

Ye Nan was a little depressed. But I had to make do with it first. Anyway, as long as he advances to the middle stage of Jindan. Otherwise, it is possible to open the enchantment of the Sealed Demon Valley. Inside the land is extremely rare grass fruits, amethyst elm and the like. It should be indispensable. When the time comes, just get some more!

I think of the Sealed Demon Valley, which is full of all kinds of treasures. Ye Nan couldn't help but get excited again. This time, the earth pill was refined. As long as you can maintain it until you advance to the middle stage of the Jindan, it's fine. When the time comes, get back the elixir in the Sealed Demon Valley. Practice again!

Ye Nan froze. Then he began to prepare for the alchemy. Carefully turned on the ground fire control switch on the hydroxide tank. Control the temperature of the Dan furnace at 500 degrees!

The fire of alchemy. Text before martial arts. It is the secret of alchemy. Start with a simmer at a temperature that is not too high. Then it is added with the drug. Increase the temperature gradually. Reach a suitable high temperature. It's a fire. Finally, it was time to condense the Dandi. Then gradually lower the temperature of the fire. It is written for the sake of re-martial arts.

Ye Nan has increased the number of alchemy in recent years. This refining pill. It is more and more proficient.

With the opening of the fire control switch, the alchemy furnace without a lid began to emit a faint heat in the furnace, with a slight whistling sound, the temperature in the furnace became higher and higher, and the temperature count displayed on the touch screen was beating rapidly, but it reached five hundred degrees in five seconds!

Ye Nan nodded with satisfaction, this Nebula Pill has extremely high requirements for fire, one is the temperature control of fire, and the other is the purity of fire!

In the past, when refining an elixir of this level, in addition to finding a pure earth fire eye, a master of the major fire type earth gold pill would generally need the assistance of a master who majored in the fire system to help control and adjust the fire temperature. That's foolproof!

And Ye Nan has this modern high-tech alchemy furnace at this time, as for adjusting and controlling the fire temperature, he doesn't have to worry about it at all, as long as it is adjusted on the control panel, the temperature will be automatically controlled for a while!

As for the purity of the fire, there is no need for Ye Nan to worry about it, this alchemy furnace uses hydrogen and oxygen flames as the flame of refining Xingyun Dan, which is the most suitable!

The most important thing is that the oxygen flame is extremely pure, there will be no impurities left after complete combustion, and it does not contain too much of the dryness of other flames, and it has the best effect on the refining of the main water cloud grass of the Nebula Pill!

Everything was ready, Ye Nan carefully took out the auxiliary medicine Extremely Rare Herb Fruit, threw the last few into the Dan furnace in one go, and then took out a jade bottle more than a foot high from the ring, carefully poured a little crystal fragrant liquid into it, and then closed the lid of the Dan furnace, and then set the time in the computer.

Ye Nan's pouring into the ground is the ten thousand years of empty green that he finally knocked out from the Baicao Gate back then, this ten thousand years of empty green contains a very strong aura, and it is also an excellent alchemy blending agent, this time it is used to reconcile these several elixirs, but it is extremely suitable!

Moreover, this medicine can also enhance the efficacy of the pill, and maybe even increase the rate of becoming a pill! At this critical time, of course, Ye Nan will not be stingy with this!

These 10,000-year-old empty green and extremely rare grass fruits need to be simmered for half an hour, that is, an hour, set the time, Ye Nan slowly moved a chair for himself, and then took out a bag of melon seeds and a pot of hot tea from the ring, and then sat in front of the big screen in the basement, turned on the screen, and the big screen displayed the situation around the entire secret service at this time.

Looking at the time, it was dinner time, and there was still half an hour before it got dark, so Ye Nan leisurely drank tea and melon seeds, while adjusting the angle of the screen, observing the defense situation of the secret service from all directions.

Looking at the guards displayed above, Ye Nan nodded slowly, on the wall outside the special service building, every five meters, there was a special combat team member with a gun, and there was also a squad of special service members, who were constantly scattered around the entire building

At the top of the building, there is also a special service team and more than 20 special combat personnel, fully armed on the roof of the building, guarding cautiously everywhere.

At the same time, Hu Xiao also sat cross-legged on the top of the building with her eyes closed at this time, her divine sense should be extremely sensitive at this time, and the slightest disturbance near this secret service should not be able to hide her from the ground!

As the sky gradually darkened, the sky gradually became dark, and the spotlights on the fence had all been turned on, plus a few mercury ceiling lamps on the roof of the building, which were not visible at a distance of 300 meters around the secret service!

Immediately after that, the screen showed that the numerous detectors around the fence and around the building had all been turned on, and as long as someone did not carry identification signs and entered within 100 meters of the secret service, the alarm would inevitably be alarmed.

Look at this almost impregnable defense

Ye Nan smiled slowly, if this still allows the blood clan secret service, then our Zhongnan secret service will directly smash the brand to make firewood.

With the bag of melon seeds finished, the Dan furnace also began to gently sound the soft sound of "Du Du Du" at this time, Ye Nan stood up gently, removed the lid of the Dan furnace, smelled the fragrance inside, and nodded with satisfaction.

Then carefully took out the amethyst elm from the jade box next to him, threw it into the Nadan furnace, and watched the amethyst elm melt away as soon as it entered the pale cyan solution of the Nadan furnace, Ye Nan covered the Dan furnace again, waiting for the two flavors of auxiliary medicine to fuse with each other.

Each of the flavors of this Nebula Pill was an immortal elixir with extremely sufficient spiritual energy, and it took a lot of effort to fuse their potency together.

The first two flavors of medicine are okay, usually about the same in an hour, but with the increase of one flavor medicine, each time this one flavor medicine is added, the fusion time will almost double!

Therefore, it would take almost two hours for this amethyst elm to completely fuse with the first extremely rare grass fruit.

It is not difficult to integrate the first few flavors of adjuvants, but when it comes to the later flavors of the main drugs, it will be much more troublesome.

It took Ye Nan almost half of the night to successfully fuse the medicinal effects of three Extremely Rare Grass Fruits, three Amethyst Ground Elms, and three Extreme Ice Lotus, and the effects of the three auxiliary drugs. And the next thing is to add the flavor of water cloud grass to it.

The potency of the Water Cloud Grass is much stronger than the effect of ordinary immortal elixirs such as the Extremely Rare Grass Fruit and Amethyst Ground Elm, and the time it takes to integrate it into that mass of medicinal liquid is also extremely large.

At the same time, the matters to be paid attention to are also extremely troublesome, because the effect of the water cloud grass is extremely powerful, from the beginning of the water cloud grass into the furnace, Ye Nan must always stare at the reaction of the liquid medicine in the furnace, and adjust the temperature in time according to the reaction of the liquid medicine.

This is something that the computer can't help him to automatically regulate, so he can only stare at it, and once it's right, he will manually adjust the fire temperature to help the liquid fusion!

Ye Nan looked at the five-leaf water cloud grass in the jade box in his hand, gently removed the two leaves, then closed the lid of the jade box, threw the two leaves into the Dan furnace, and then immediately closed the lid of the furnace.

Ye Nan then gently knocked twice on the control panel, and soon the top cover of the Dan furnace lifted a small board, and under the small plate was a piece of high-strength heat-insulating glass, which allowed people to see the liquid medicine in the Dan furnace smoothly.

Ye Nan sat on the edge of the Dan furnace, carefully watching the fluctuations of the medicinal liquid in the Dan furnace, for fear that something would be abnormal.

This was the first time he had refined such a high-grade elixir, so he was a little nervous, seeing that the water cloud grass was suspended in the high-temperature medicinal liquid, without the slightest appearance of melting, Ye Nan had to sigh.

This high-level elixir is indeed extremely difficult to refine, and the huge spiritual power of this water cloud grass is unwilling to be integrated into that medicinal liquid like this, so it seems that it has to continue to strengthen its firepower.

Ye Nan looked at the movement of the water cloud grass inside, and gently pressed the temperature adjustment button on the control panel, as the temperature displayed on the control panel became higher and higher, the contact part between the water cloud grass and the medicinal liquid gradually began to emit some fine gas.

Seeing these qi coming out, Ye Nan breathed a sigh of relief slightly, and this water cloud grass finally began to dissolve at a high temperature, and gradually began to merge with the medicinal liquid.

Ye Nan looked at the temperature displayed on the control panel, but at this time, it had already been displayed to 1,200 degrees Celsius!

Seeing the display of this value, Ye Nan chuckled with satisfaction, secretly saying that fortunately, the group of guys in the equipment department were bored to make such an alchemy furnace, otherwise it would be an extremely troublesome thing to refine the alchemy by themselves.

Not only did this earth fire source have to be borrowed from some big factions, but it also had to pay some great price and ask some masters of the Fire Spirit Sect to help.

And now, I just spent 8 million yuan to buy this Dan furnace, but it is very convenient, and I don't need to spend a lot of money to ask others, which is really refreshing.

Ye Nan stared at the Dan furnace, but the time passed minute by minute, after a long time, although this water cloud grass has been bubbling some gas, but it has melted very little, after nearly half an hour, this water cloud grass floats in the medicinal liquid, still water and water spirit, it doesn't seem to have changed much.

Ye Nan frowned lightly, and then continued to press the heating button, continuing to heat up the Dan furnace. Ye Nan stared at the changes in the liquid medicine in the Nadan furnace, his fingers kept pressing, and the temperature of the furnace began to heat up gradually. In just a short time, it soared to 1,500 degrees Celsius!

Ye Nan was staring at the Dan furnace here, and the old ghost on the roof of the secret service outside was also gently floating on the roof at this time, his eyes slightly closed, and his hands were holding a magic trick, slowly absorbing the faint Xuanyin Qi in the night sky.

The special service members of a small team and the two teams of special combat personnel not far from the old ghost were now cautiously staring at him with guns in front of him, observing the wind and grass in his field of vision, for fear that something would sneak into the secret service without his own defense.

Speaking of which, they also felt a little resentful, they had never been in their own nest like this for so long in the secret service, and they had to be so cautious. I think back then, when the demon clan often attacked the secret service, they were never so cautious, but today I feel it.

However, they also know what kind of enemy the secret service is facing now, that is a senior vampire prince who is a step above the average gold master, and it is said that even Director Ye, under the sun, has not been able to take this prince well.

This made these secret service members who had always regarded Ye Nan as a god secretly frightened, how terrible it must be that a vampire who could tie with Director Ye under the sun. If it's night, I don't know how powerful it will be!

Therefore, these special service members, at this time, they all dare not slack off, and are cautiously guarded, otherwise if this is stationed in their own special service province, and they are easily attacked by others, then they really have no face to go out and mix!

At this time, it was almost three o'clock in the morning, and soon a team of special service members and special combat personnel walked out of the special service building, and they were here to take over.

Seeing that the successor colleagues were coming, these special combat personnel immediately turned around and gave up the sentry post, so that the successor colleagues could stand on the sentry post. Then he exhaled white air and ran towards the building.

It was already close to the cold winter of January, and the night was extremely cold, but under this night sky, the temperature was close to freezing.

Fortunately, the combat uniforms equipped by the special service members and special combat personnel are all cold performance

Special equipment, standing on a post for three hours like this, for them, it is hard work, just to concentrate on guarding, but it is still extremely exhausting!

At this time, the special services and special combat team members who took over were much more relaxed in their hearts, it was already past three o'clock, and it should be calm today, and in such weather, that damn vampire should not come out.

However, things were not as they thought, outside the range of the security lights of the secret service, a black shadow was quietly lurking in the darkness and did not move, only a pair of blood-red eyes, from time to time flashed a faint murderous gaze!

Prince Fa Ge hid behind a big tree, very reluctant to look at the strong warning light, low roar, he has been lurking here for two hours, but the strong light and the snipers on the fence and the old guy on the roof, have never let their guard down, which makes him always unable to attack smoothly.

Up to now, these boys who have just taken over are in good spirits one by one, and it seems that it is not easy to sneak attack.

And according to the situation I saw during the day, there is the female demon clan and the old guy now, it seems that in this secret service building, there are at least two masters who are almost at the Jindan level. Even if I sneak in, I'm afraid that I can only get anywhere.

Prince Fage looked up at the cold moonlight that had already slanted to the west, but his eyes were getting redder and redder, he was not willing to suffer the cold here all night in vain, and he had to make those guys pay some price!

Prince Fage stared at the several heavily armed and guarded warriors in front of him, he was only waiting for an opportunity, as long as the other party was slightly distracted, he would rush over, and even if he didn't get much benefit at that time, he could at least kill a few ants to let himself vent.

After a while, Prince Fago's eyes gradually brightened, and he clearly saw that one of the warriors opposite him seemed to be yawning, and the two warriors next to him were indeed slowly scanning towards his sides.

"One, two, three!" Prince Fa Ge was extremely experienced, and he quickly grasped the moment when this special combat member yawned and rushed over.

At this time, the other two special combat team members had already turned their eyes to the side, and the only special combat team member in the middle who could react quickly squinted his eyes in the second or two of yawning.

It's doomed, his yawn is killing him!

When he opened his eyes, one paw was already in front of his eyes, and before he could react, his eyes turned black and he felt nothing. It's just that at this moment, I faintly heard a sharp alarm sounding suddenly!

At this time, Ye Nan had just raised the temperature in the interior of the Dan Furnace to more than 1,600 degrees, and the water cloud grass had finally begun to turn into a pale green viscous liquid, but it still hadn't fused with the other cyan medicinal liquids.

However, seeing this scene, Ye Nan breathed a sigh of relief, this water cloud grass has finally melted, but it has to be completely fused with other medicinal liquids, but it still needs a long time of refining before it is possible!

Of course, as long as the herb is fused into the entire medicinal liquid, the procedure after that is much simpler.

It's just that this fusion process is also extremely careful, Ye Nan has gradually begun to slowly lower the temperature in the furnace at this time.

This water cloud grass has melted, so the temperature no longer needs to be so high, otherwise if it continues at such a high temperature, it is easy to make the medicinal liquid in the Dan furnace lose part of its spiritual effect.

Of course, this is also the time to test the skill of an alchemist, but this is not difficult for Ye Nan at all, all he has to do is carefully look at the medicinal liquid in the Dan furnace and gently press the temperature adjustment button.

However, before he finished adjusting the temperature, the alarm light on the big screen flashed quickly, and at the same time, a picture touching the alarm position flashed quickly.

Seeing that black shadow quickly overturned the two special combat soldiers, and then was temporarily forced back by a dozen sniper rifles to take a small step, Ye Nan couldn't help but exhale lightly, he couldn't imagine that this vampire prince was so impatient, suffered a loss during the day, and was actually alone, and he came to sneak attack this night, and he was really cautious enough!

It's just a pity that his two special combat team members were reimbursed by his two claws!

At this moment, another black shadow quickly appeared in the picture, appeared in front of the vampire prince, picked up a long knife and slashed at the vampire prince.

Ye Nan Dingqing saw that it was the old ghost on duty, this old ghost reacted quite quickly, it seemed that he reacted in less than two seconds, and rushed to the vampire prince from the top of the building.

It's just that this vampire prince's strength at night is indeed obviously a lot more than during the day.

With the strength and reaction speed of the old ghost Xuanyin's indestructible body, he was actually slashed back by the vampire prince for as many as two or three steps, and this vampire prince, with that strange-shaped long blade, was still slashing at the old ghost with his head and face.

The long blade waved, and under the shooting of the special service's coarse, high-definition and sensitive high-speed camera, it was all a silver shadow, and he couldn't see the speed of his knife, but the old ghost who watched it at this moment retreated at least five or six meters away, and he was very embarrassed!

Looking at this situation, Ye Nan shook his head and sighed while carefully adjusting the temperature control button at hand, thinking to himself that in such a close-quarters tactical situation, it was absolutely impossible for him to force the old ghost with the Xuanyin Immortal Body to such a point. It's good to be able to barely gain the upper hand.

Ye Nanzheng was nervous, but fortunately, this decline was quickly brought back when support arrived.

Fang Wei, who was assisting in the night shift, had already rushed out of the building at this time, but the spirit dragon had already roared angrily and slammed into the vampire prince.

At this time, the prince of Fa Ge was venting his anger during the day towards the old ghost, but this old ghost, whose melee strength was still very strong, forcibly blocked him with all his strength and stabbed him, but he was not injured at all

Fa Ge was furious by this situation, but at this moment, he was stunned to see that a powerful force slammed into him next to him!
